To all whom it may concern:

Be it known that I, HAsoAL A. Hocnr., a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Pumping Apparatus;and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to improvements in pumping apparatus, andis especially intended to provide a pump automatically operated bycompressed air, which is adapted to force water, oil, or other liquid,to a considerable height.

The apparatus contained in my invention comprises one or more pairs ofcylinders to which the compressed air and water are alternatelyadmitted, and from which the air or water is alternately expelled by theautomatic apparatus herein described and claimed.

The construction disclosed herein embodies -certain changes over thearrangement proposed in the construction shown in my co-pendingapplication on a similar invention Serial No. 570,891, and dated July 5,1910.

Reference is had to the accompanying drawings, in which the same partsare indicated by the same letters throughout the several views.

Figure 1 is a side elevation of the apparatus showing two pumpingchambers one being` shown in central vertical section. Fig. 2 is an endview of the apparatus shown in Fig. 1. Fig. 3 is a sectional plan, on asmaller scale, showing the arrangements of pipes for conveying liquid,and, Fig. 4: shows a modification in which a rolling ball is usedinstead of a quantity of mercury.

A and A represent two closed pumping chambers, each of which isconnected, as by pipes B and B', to an eleva-ted source of liquidsupply, so that the liquid will flow by gravity into the chamber whenthere is no air pressure on.

C represents a pipe opening into the bottom of the chamber, throughwhich the liquids flows alternately in reverse directions.

D is an outlet pipe for the liquid, connected tol the pipe D', openinginto the delivery pipe E.

Check valves b and el are provided in the liquid inlet and out-letpipes, the former opening inward and the latter opening outward, asshown in Fig. 2.

F represents a manhole cover, secured to the top of the chamber, and isprovided with a stuffing box j", through which runs the rod h, connectedto the iioat H, which is provided with guide lugs h2, engaging the guiderods G secured to the manhole cover F.

A I is a frame connected to the two receptacles and preferably providedwith rubber spring buffers z', as shown in Fig. 1.

M is a rock shaft, to which is rigidly attached the frame N and therocking arms Q and Q, each having a bent in end g, see Fig. 1. The frame1T is provided with a shoe N, having curved ends n, and with guide rodsi 2 to hold the end pieces N3 in which the iron or steel tube P ismounted. In this tube, a quantity of mercury O is placed. Instead of themercury in the tube, a ball O, shown in Fig. 4C, may be provided,running between the guide rods N2.

S represents a pipe, connected to a suitable source of supply ofcompressed air, not shown. This pipe leads to a cross having fourpassages therethrough, controlled by the four way cock R2, operated bythe pin R on the crank R. Connected to this cross, lin addition to thesupply pipe S, are the branch delivery pipes S and S2 and the eX- haustpipe S3, shown most clearly in Fig. 1.

The parts should preferably be covered by a suitable hood, such as isshown in dotted lines at T, and this hood may be provided with eye boltst for convenience in hoisting into and out of position when desired.

The operation of the device is the same whether the mercury is used orwhether the ball is used, and is as follows The frame N and the arms Qand Q', all rocking together, may be conveniently known as a tumblingbob, and this is alternately rocked automatically, as will now bedescribed. Suppose the two floats H and H to be in the positionindicated in Fig. 1, and the top of the chamber A to be connected to theexhaust pipe S3, and the top of the chamber A to be connected to thesupply pipe S. The liquid will rise under gravity in the chamber A,lifting the corresponding check valve Z), while at the same time the airpressure will close the check valve of the chamber A and will open thevalve d of said chamber, forcing the liquid out and up into the deliverypipe E. As the liquid rises in the chamber A, it will in due time reachthe iioat H and lifting same will cause the roll ers L to engage thecurved end a of the shoe N. rlhis will gradually rock the tumbling bobuntil it is just past the horizontal position, when the mercury, or theball, running down toward the opposite end of the frame N, will swingthe tumbling bob rapidly, causing the end g of the arm Q to strike theroller 1 on the pin R, and swinging the arm R and the four-way cock R2suddenly, will turn on the air pressure to the chamber A and willconnect the chamber A to the exhaust. The liquid will now begin to risein the chamber A, and to flow from the chamber A, being forced. out bythe air pressure and up into the pipe E. As the float H rises, itscorresponding roller L will engage the opposite end of the shoe N andwill swing the tumbling bob in the reverse direction, the operationbeing again reversed. The cycle of operations will continue indefinitelyas long as there is a source of supply of liquid and another source ofsupply of compressed air.

lt will be seen that l provide a simple and effective arrangement bywhich compressed air may be used automatically to pump liquid to thedesired height.

It will be obvious that various modiiications might be made in theherein described apparatus, which could be used without departing fromthe spirit of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is l. A pumping apparatus comprisinga pair of closed vessels, a source of liquid supply' communicating withsaid vessels with check valves controlling said liquid; a source ofsupply of compressed air connected to both of the vessels, a verticallymovable float mounted in each of said vessels, a piv oted rocking frameprovided with a track curved at the ends, a sliding weight mounted insaid rocking frame, and adapted to travel by gravity backward andforward therein as said frame is rocked, a rod connected to each floatand having a roller engaging said track on the rocking frame, and meansoperated by said frame for` admitting compressed air alternately to eachof said vessels and for simultaneously allowing the compressed air toescape i rom the other vessel, substantially as described.

2. A pumping apparatus comprising a pair of closed vessels, a source ofliquid supply communicating with said vessels with check valvescontrolling said liquid; a source of supply of compressed air connectedto both of the vessels, a vertically movable float in each of saidvessels, a pivoted rocking frame provided with a track curved at theends and also with inclined downwardly projecting arms, a sliding weightmounted in said rocking frame, and adapted to travel by gravity backwardand forward therein as said frame is rocked, and a four-way cockoperated by said arms for admitting compressed air alternately to eachof said vessels and for simultaneously allowing the compressed air toescape from the other vessel, substantially as described.

3. A pumping apparatus comprising a pair of closed vessels, a source ofliquid sup-4 ply communicating with said vessels with check valvescontrolling said liquid; a source of supply of compressed air connectedto both of the vessels, a vertically movable float in each of saidvessels, a pivoted rocking frame provided with a track curved at theends and also with inclined downwardly projecting arms, a ball mountedin said rocking frame, and adapted to roll by gravity backward andforward therein as said frame is rocked, and a four-way cock operated bysaid arms for admitting compressed air alternately to each of saidvessels and for simultaneously allowing the compressed air to escapefrom the other vessel, substantially as described.

In testimony whereof, I afliX my signature, in presence of twowitnesses.
